Abstract: PURPOSE:To obtain an entitled support superior in antistatic effect and water- resistance, by forming a conductive layer having a specified surface resistivity between paper and a thermoplastic polymer-coated layer contg. a white type pigment. CONSTITUTION:One or both sides of 30-500mum thick paper are coated with a mixture of a conductive crystalline metallic (composite) oxide, such as ZnO, having 0.01-0.7mum particle diameter, and a binder, such as gelatin, so as to control said oxide to 0.05-10g/m<2> to obtain a conductive layer to <=5X10<7>ohm surface resistivity. The obtained conductive layer is coated with thermoplastic polymer having 20,000-200,000mol.wt. such as polyethylene, contg. a white type pigment in 10-100mum thickness to form a thermoplastic polymer-coated layer. As a result, the obtained photographic printing paper support gives no adverse effect on photosensitivity of its silver halide emulsion layer, reduces occurrence of edge stains during processing, and retains sufficient antistatic effect even in severe conditions, such as low humidity.

Title: Method and device for automatic rising vertical electrogas arc welding
Inventor: NOMURA HIROICHI
IPC: B23K9/173
Filed: 1983-01-18
Abstract: PURPOSE:To rise automatically and intermittently a sliding copper strap together with a torch in synchronization with the rising of a molten metal surface by making a wire feed speed constant and controlling a motor for rising the torch and the sliding copper strap in such a way that the detected value of welding current or arc voltage attains the value within a reference set range. CONSTITUTION:Vertical welding is performed from below to above while an electrode wire 7 is fed with a torch 6 by enclosing and supporting a molten pool 3 with a stationary copper strap 4 on the rear side of the groove and a sliding copper strap 5 on the front side of base metal 1. A welding curriage is stopped when the welding current is equal to a reference value I0 and the wire extension is Ex0. As welding progresses, the surface of the pool 3 rises and the wire extension is retracted to Ex1. Since the wire feed speed is constant in this stage, the welding current increases and the arc voltage decreases. Therefore if, for example, the welding current is detected in this state, it is I1>I0. The permissible range DELTAI of the current is set with respect to I0 and when I1-I0>DELTAI is attained, the strap 5 and the torch 6 are moved upward integrally and the carriage is stopped when I1-I0<DELTAI is attained.

Abstract: PROBLEM TO BE SOLVED: To suppress the generations of the broken edge portions of a wafer and its cracks, by making the horizontal distance ranged from the end of its flat surface to the end of its post-grind edge portion smaller than its post-grind thickness. SOLUTION: A wafer 1 of T in thickness has its end surface 3 of a rounded shape. After forming device elements on its flat front surface 1A, when grinding its flat rear surface 1B to make its thickness equal to a specified thickness of t, a horizontal distance L ranged from end portions (points P, Q) of its flat surfaces 1A, 1B to an end 5 of the edge portion of a post-grind wafer 2 is made smaller than t.

Abstract: PURPOSE:To attain a high speed distance calculation between strokes by approximating the stroke by the number of dots according to the length thereof and obtaining a corresponding dot by thinning out the dots. CONSTITUTION:The stroke is dot approximated by any number of dots on a sequence Wk correspondingly to the length and in the correspondence of the dots between the strokes having the different number of dots, approximate dots are thinned out from the stroke having the large number of approximate dots and after the number of the approximate dots is set, a matching between the strokes is taken. In a rule for thinning out, the number of the approximated dots is represented by the sequence Wk and the thinning out is carried out by making the difference of (k) of the strokes as an unit. For instance, when one stroke is approximated by W4 dots and the other stroke is approximate by W3 dots, the set of the strokes is (W4, W3) and the difference in (k) is 1, so that one dot is respectively thinned out. Thereby, the high speed distance calculation between the strokes can be attained.
